Five weeks ago whilst helping my mother in law Susan decorate her lounge, she came onto me and we ended up fucking pretty much the whole afternoon. The sex was wild, really dirty and just anything was on the cards. Susan told me she'd wanted me to fuck her, ever since she walked in on her daughter and I having sex. I was fucking her, in her old bedroom two years ago when her mum opened the door to see me screwing her daughters arsehole from behind. After the sex with Susan, we both agreed it was a one off, even if and these were her words "You're the horniest fuck I've ever had".
Susan really is an attractive forty three years old woman, and in many ways is much sexier than her daughter. She's also going off our afternoon five weeks ago, a much better fuck.
Now to my problem. Her daughter has invited Susan to stay over during the whole of the Christmas and New Year period. As soon as Susan got the invite two days ago, she text me to say, all bets are off as to her and me screwing again. She knows her daughter will have to work on some of the days she's here, and she also knows I'm off the whole of the time.
I love my wife and enjoy our life together, but her mum is such a wonderful dirty fuck. That's why I just don't know if I'll be able to say no, if she strips naked in front of me again.
God I'm hard now just thinking of Susan's stunning body and her large swollen suckable clit.
